오류 업데이트 SQLite는 안드로이드 I 데이터베이스 MS_EVENT_CONFIRMATION에 테이블이

Question

,이 표는 3 열 구성

MEMBER_USERNAME

EVENT_CONFIRMATION

을 EVENT_ID

1. 그리고 코드를 만들고 싶어 EVENT_CONFIRMATION 열을 업데이트하려고했지만 오류가있어 항상 그런 열을 말하지 않았습니다 : ...
   나는 데이터베이스에 내 활동에서 데이터를 전달하려는 경우

   String defaultConfirmation = "pending"; 
       String Query = "SELECT * FROM " + MS_GROUP_DETAIL + " WHERE " 
         + GROUP_ID + "=?"; 
   
       Cursor c = ourDatabase.rawQuery(Query, new String[] { groupId }); 
       int iMember = c.getColumnIndex(MEMBER_USERNAME); 
   
       String username = ""; 
   
       ContentValues cv2 = new ContentValues(); 
   
       for (c.moveToFirst(); !c.isAfterLast(); c.moveToNext()) { 
        username = c.getString(iMember); 
   
        if (!checkConfirmation(eventId, username)) { 
         cv2.put(EVENT_ID, eventId); 
         cv2.put(MEMBER_USERNAME, username); 
         cv2.put(EVENT_CONFIRMATION, defaultConfirmation); 
         ourDatabase.insert(MS_EVENT_CONFIRMATION, null, cv2); 
        } 
       } 
   

   이것은 :

   내가 같은 테이블을 삽입 할 곳입니다

    db.execSQL("CREATE TABLE IF NOT EXISTS " + MS_EVENT_CONFIRMATION 
          + "(" + EVENT_ID + " INTEGER, " + MEMBER_USERNAME 
          + " TEXT, " + EVENT_CONFIRMATION + " TEXT, PRIMARY KEY(" 
          + EVENT_ID + ", " + MEMBER_USERNAME + "), FOREIGN KEY (" 
          + MEMBER_USERNAME + ") REFERENCES " + MS_MEMBER + "(" 
          + MEMBER_USERNAME + "), FOREIGN KEY (" + EVENT_ID 
          + ") REFERENCES " + MS_EVENT + "(" + EVENT_ID + "));"); 
   

   테이블 만들기 :여기 내 코드입니다 :

    case R.id.bDoAttendingEvent: 
        AlertDialog.Builder builder = new AlertDialog.Builder(this); 
        builder.setMessage("You choose to attend this event?") 
          .setCancelable(false) 
          .setPositiveButton("Yes", 
            new DialogInterface.OnClickListener() { 
             public void onClick(DialogInterface dialog, 
               int id) { 
              myDb.open(); 
              string = "attend"; 
              myDb.confirmEvent(eventId, Username, string); 
              attend.setBackgroundColor(Color.BLUE); 
              notAttend.setBackgroundColor(Color.GRAY); 
              confirmation.setText("Confirmation : Attend"); 
              myDb.close(); 
   
             } 
            }) 
          .setNegativeButton("No", 
            new DialogInterface.OnClickListener() { 
             public void onClick(DialogInterface dialog, 
               int id) { 
              dialog.cancel(); 
             } 
            }); 
        AlertDialog alert = builder.create(); 
        alert.show(); 
        break; 
   

   그리고 데이터베이스 파일은 다음과 같습니다. ',992,967,

   public void confirmEvent(String eventId, String username, String string) { 
       // TODO Auto-generated method stub 
       ContentValues cv = new ContentValues(); 
       cv.put(EVENT_CONFIRMATION, string); 
   
       ourDatabase.update(MS_EVENT_CONFIRMATION, cv, MEMBER_USERNAME + "=" 
         + username + " AND " + EVENT_ID + "=" + eventId, null); 
   
   }

   당신이 내 실수 어디 말해 도와 주시겠습니까?

Answer 1

는 SQL에서이

ourDatabase.update(MS_EVENT_CONFIRMATION, cv, MEMBER_USERNAME + "=" 
    + "'" + username + "'" + " AND " + EVENT_ID + "=" + eventId, null); 

을 시도하십시오 사전에 감사합니다, 문자열 리터럴은 인용해야합니다.
